Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84578, here are decompositions:

19 + 84559 = 84578
79 + 84499 = 84578
97 + 84481 = 84578
157 + 84421 = 84578
229 + 84349 = 84578
271 + 84307 = 84578
331 + 84247 = 84578
349 + 84229 = 84578

Showing the first eight; more decompositions exist.
